Description

Acid Red 138 is a dye that is used in the process of wastewater treatment. It has been shown to be effective as a polarizer and as a cross-linking agent for calcium carbonate. Acid Red 138 can also be used as a polymerization initiator for reactive sodium carbonate. The compound is stable at high temperatures, but reacts with potassium permanganate and can be degraded by radiation or chemical interactions. Acid Red 138 has been shown to form an equilibrium phase with sodium carbonate at high concentrations.
